Geometry group Flip YZ-axis When on, transfers all Y-axis values to the Z axis and vice-versa. Use this when exporting to Poser and other programs that use Y as the vertical axis and Z as the depth axis. Shapes/Lines Enables export of splines and NURBS curves. NOTE NURBS curves are exported as splines. Hidden Objects When on, hidden objects are exported. Faces Choose whether the mesh faces are stored as triangles, quadrangles, or polygons. Texture coordinates When on, texture coordinates are stored with the exported file. When you import the file in another application you will be able to use this information if it is supported. Normals When on, the normal information on page 8059 for the mesh is stored. Smoothing groups When on, the information about color transition between groups is stored. See Viewing and Changing Smoothing on page 403. Scale Determines the scaling for the contents of the OBJ file. The default value of 1.0 means no scaling is performed. Material group Use material Determines whether the materials associated with the scene objects are also exported to the OBJ file. Create mat-library Determines whether the exporter creates a separate file to store information about the materials. This creates a MTL library file in the same directory as the OBJ file. If Use Material is on but Create Mat-library is off, the OBJ file contains a reference to a like-named MTL file, but the MTL file is not saved. Use this to save time if the MTL file already exists. Force black ambient Sets the Ambient component of exported materials to black. Map-Export Click to open the Map-Export dialog on page 7288 Wavefront (OBJ, MTL) Files | 7283
